the relative profitability of Cournot vs. Bertrand when a per unit royalty is applied. By contrast, we find that Cournot … yields higher profits than Bertrand under ad valorem royalties, regardless of the strength of network effects. …

In this paper we investigate the effects of delinquency and arrest on school leaving using information on males from the National Longitudinal Survey of Youth 1997. We use a multivariate mixed proportional hazard framework in order to account for common unobserved confounders and reverse...

Classical definitions of complementarity are based on cross price elasticities, and so they do not apply, for example, when goods are free. This context includes many relevant cases such as online newspapers and public attractions. We look for a complementarity notion that does not rely on price...

We propose a novel method to model an agent who is imperfectly attentive in the sense that she may consider only some of the alternatives available. Our methodology departs from the standard 'revealed preference' one: we make plausible assumptions on the values to the imperfectly attentive agent...

Risk taking is an important topic in Africa, as access to financial institutions and social security is scarce. Data on risk attitudes in Africa is limited and the available data collected might not be reliable. We investigate the determinants of risk attitudes and the reliability of survey data...

A sequentially rationalizable choice function is a choice function which can be obtained by applying sequentially a fixed set of asymmetric binary relations (rationales). A Rational ShortlistMethod (RSM) is a choice function which is sequentially rationalizable by two rationales. These concepts...

The U.S. economy had experienced the "jobless recovering" after the 1990-1991 and 2001 recessions, which has been constantly puzzling the economists, market analysts, and policymakers. This paper uses a simple hiring game in an efficiency wage model framework to resolve that puzzle. Our...

This paper presents new evidence on the distribution of risk attitudes in the population, using a novel set of survey questions and a representative sample of roughly 22,000 individuals living in Germany. Using a question that asks about willingness to take risks on an 11-point scale, we find...

We study a psychologically based foundation for choice errors. The decision maker applies a preference ranking after forming a 'consideration set' prior to choosing an alternative. Membership of the consideration set is determined both by the alternative specific salience and by the rationality...

We propose an extension of Tversky's lexicographic semiorder to a model of boundedly rational choice. We explore the connection with sequential rationalisability of choice, and we provide axiomatic characterisations of both models in terms of observable choice data.
